What is an element give 3 examples?
An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium . An important number in an element is the atomic number.
What are elements examples?
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. There are 92 naturally occurring elements and everything in the universe is made from these basic building blocks. Common examples include carbon, sulfur, oxygen, iron, copper, aluminium .
What are the elements 2?
Helium is the element that is atomic number 2 on the periodic table. Each helium atom has 2 protons in its atomic nucleus. The atomic weight of the element is 4.0026. Helium does not readily form compounds, so it is known in its pure form as a gas.
